Reset to default 6Use the onkeyup event:
let element = document.querySelector('your element');
element.onkeyup = function () {
if (this.value.length > 10) {
myFunction();
}
}
You also use this in an attribute:
<textarea onkeyup="if (this.value.length > 10) myFunction();"></textarea>
EXAMPLE (for both)
/* go automatic do the next tabindex */
$(":input:not(:disabled)").not($(":button")).keyup(function(evt){
if (this.value.length == 1) {
currentTabindex = $(this).attr('tabindex');
if (currentTabindex) {
nextInput = $('input[tabindex^="'+ (parseInt(currentTabindex)+1) +'"]');
if (nextInput.length) {
nextInput.focus();
return false;
}
}
}
});
